From my experience, private corporations who are required to meet Section
508 compliance accessibility standards respond much quicker to "this is
what Section 508 will be, so it's best to code accordingly" and align the
work to the draft and WCAG 2 than to sell WCAG 2 as a universal standard.
We may argue that these are semantics, but such distinctions matter when
you're making the case with executive leadership and putting a lot of money
towards that solution.
